Only Isolated Showers Today; Big Cool Down This Weekend

| October 12, 2021 @ 5:49 am

RADAR CHECK: We have a few small, isolated showers over Northwest Alabama early this morning ahead of a surface front that will stall out northwest of Alabama. We will mention the chance of small, spotty showers today over the northern half of the state, but the chance of any one place seeing rain is only 10-20 percent. Otherwise, today will be warm again with a mix of sun and clouds… the high will be in the mid 80s. The average high for Birmingham on October 12 is 78.

The weather will be warm and dry tomorrow and Thursday; with a good supply of sunshine both days afternoon temperatures will reach the mid 80s.

FRIDAY AND THE WEEKEND: Most of the day Friday will be dry, and we stay warm with mid 80s likely again. But, clouds will increase during the day, and we will mention a chance of showers Friday night and Saturday morning, generally from 6:00 p.m. Friday through 9:00 a.m. Saturday. These showers are ahead of a sharp cold front that will bring a big change to cooler weather for the weekend. The sky becomes partly sunny Saturday afternoon, but the high will be in the 68-72 degree range with a fresh north breeze.

Temperatures will fall into the 40s over most of North/Central Alabama early Sunday, and the day Sunday will be a picture perfect autumn day with ample sunshine along with a high in the upper 60s and low 70s.

NEXT WEEK: For now the week looks mostly dry and very pleasant with highs mostly in the 70s, and lows in the 50s. See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: The Atlantic basin is generally quiet this morning. Weak disturbances near Hispanolia and the Windward Islands are not expected to develop. Over in the eastern Pacific, Pamela is now a hurricane, and the center is about 260 miles south/southeast of the southern tip of Baja California. Sustained winds are 75 mph, and landfall is expected on the Pacific Coast of Mexico late tonight or early tomorrow morning.

While the system will rapidly weaken over Mexico tomorrow, moisture from Pamela will move into Texas Thursday, with potential for heavy rain in a broad zone from Del Rio to Dallas/Fort Worth.

GEOMAGNETIC STORM: A G2, “moderate” geomagnetic storm impacted the high latitudes last night and early this morning. A vivid display of the Northern Lights were seen over most of Canada and the far northern U.S. The storm was sparked by a CME, a Coronal Mass Ejection. This is a large expulsion of plasma and magnetic field from the Sun’s corona.

ON THIS DATE IN 1979: The lowest barometric pressure ever recorded occurs in the center of Typhoon Tip on this day. A fly reconnaissance mission recorded the low pressure of 870 hPa or 25.69 inHg. Typhoon Tip was the most extensive tropical cyclone on record with a wind diameter of 1380 miles at its peak.
